摘要
Dear Editor,Breeding a new wheat variety using traditional methods typically takes at least 8 to 10 years,and the breeding period can be dramatically shortened via a doubled haploid strategy,which can yield homozygotes within one or two generations.In the past several decades,wheat haploids have been widely induced through anther or microspore culture and chromosome elimination via interspecific hybridization between wheat and maize.The first technique exhibits strong genotype dependency and a severe albino phenomenon,whereas the latter shows low induction efficiency(Sangam et al.,2015).In addition,haploid induction procedures using the aforementioned methods are complicated to perform and require specialized equipment and environmentally controlled conditions.Thus,the application of these technologies in wheat breeding has been limited(Sangam et al.,2015).
